The Russian authorities announced the Turkish Stream in December 2014 to replace the South Stream gas pipeline project. It was planned that the offshore section of the Turkish Stream gas pipeline would comprise four stretches with a capacity of 15.75 billion cubic meters each.

However, the negotiations on the project were subsequently suspended, including due to the crisis in bilateral relations. After talks held between Turkish President Tayyip Erdogan and Russian leader Vladimir Putin in St. Petersburg in August 2016, a decision was made to resume the project, set up a working group and prepare a roadmap.
